When a standard pan head sits too proud and a countersunk head isn’t an option, the modified truss head delivers the ideal low‑profile clamp. Designed for fastening thin sheet metal, wood, plastics, and composite materials, these Phillips self tapping screws from GooBetter Fastener eliminate the need for separate nuts or pre‑tapped holes. The wide bearing surface distributes clamping force over a larger area — perfect for HVAC ductwork, automotive interior panels, electrical enclosures, and furniture assembly. Coated in a matte black zinc finish, they resist corrosion in indoor and light‑duty outdoor environments while blending into dark backgrounds for a cleaner look. Available from M1.2 up to M4, this assortment keeps the right size at your fingertips whether you're a professional installer or a home workshop enthusiast.

It’s a low‑profile head that combines a wider bearing surface than a pan head with less height. This design spreads clamp load to prevent pull‑through in thin or soft materials while sitting flatter against the surface — especially useful where clearance is limited.
Yes. The self‑tapping thread works well in softwoods and hardwoods alike. For very dense hardwoods, drilling a pilot hole at approximately 80% of the screw diameter will reduce drive torque and prevent snapping.
Black zinc provides good atmospheric corrosion resistance for indoor, covered, and mild outdoor environments. For constant exposure to rain, salt, or chemicals, consider a stainless steel fastener or supplementary coating.
A standard Phillips driver bit sized to match the screw head (#0, #1, or #2) works perfectly. We recommend using a bit that isn’t worn to avoid cam‑out and preserve the head recess.
